World’s smartest vacuum doubles as home security system

LG's newest Hom-Bot robotic vacuum, available this month, merges cleaning and home security into one smartphone-controlled system.

In addition to sweeping up dust and crumbs, the Hom-Bot has front and top-facing cameras that can be accessed through its app at any time. In a true representation of the "smart" vacuum, once it's become accustomed to your home, the Hom-Bot will also automatically snap photos and message them to you if it detects movement in an area of the home or at a time of the day when activity is unusual.

A square-ish rather than rounded shape allows it to edge into tighter corners, and its cameras not only act as a safety measure but also help it more accurately map the room to achieve an efficient cleaning route. Its final feature is a sure appeal to a millennial audience: The vacuum is a rose-hued shade of "metallic gold."
